Angelfish are among the most sought-after freshwater fish due to their graceful movements, striking appearance, and engaging personalities. A common question among aquarists is whether angelfish should be kept in pairs or if they can thrive alone. Understanding their social behavior is key to providing them with the best possible environment. Additionally, if you're wondering, "What Fish Can Go With Angelfish", selecting the right companions plays a crucial role in maintaining a harmonious tank.

The Social Behavior of Angelfish

Angelfish belong to the cichlid family, a group known for its intelligence, territorial instincts, and social hierarchy. While they are not strictly schooling fish, they exhibit social behaviors that make them unique.

Are Angelfish Social or Solitary?

• Juvenile Angelfish: When young, angelfish are more social and tend to stay in groups. They find comfort in numbers and are less aggressive toward each other.

• Adult Angelfish: As they mature, they develop territorial instincts. Some may become aggressive toward weaker or smaller tank mates, especially in confined spaces.

• Pair Bonding: In the wild and in aquariums, angelfish often form monogamous pairs for breeding purposes.

Do Angelfish Need a Pair to Be Happy?

Whether or not angelfish should be kept in pairs depends on several factors, including tank size, individual temperament, and the presence of other fish. Here’s a breakdown of different scenarios:

Keeping a Single Angelfish

• A single angelfish can thrive if given a spacious tank and proper enrichment.

• Without a mate, some angelfish may become less active but will still interact with their surroundings and tank mates.

• If kept alone, providing a variety of peaceful tank mates can prevent loneliness.

Keeping Angelfish in Pairs

• A bonded male-female pair will form a close relationship, often displaying protective behaviors.

• If the pair is not compatible, they may become aggressive toward each other.

• During breeding, pairs become highly territorial and may attack other fish in the tank.

Keeping a Group of Angelfish

• A group of 4-6 angelfish can coexist peacefully in a large tank (55 gallons or more).

• A larger group spreads out aggression, reducing the chances of one fish being bullied.

• As they mature, pairs may form naturally, leading to potential territorial disputes.

What Fish Can Go With Angelfish?

If you choose to keep a single angelfish or a group, selecting compatible tank mates is essential. Here are some peaceful fish that can coexist well with angelfish:

1. Corydoras Catfish – The Bottom-Dwelling Cleaners

• Stay at the bottom of the tank, avoiding competition.

• Non-aggressive and social when kept in groups.

• Help clean leftover food from the substrate.

2. Rummy Nose Tetras – Active and Peaceful Schooling Fish

• Provide movement and color without threatening angelfish.

• Best kept in groups of six or more.

• Adapt well to similar water conditions.

3. Bristlenose Plecos – The Gentle Algae Eaters

• Stay out of the angelfish’s way by sticking to the tank walls and substrate.

• Non-aggressive and help control algae growth.

• Require driftwood for digestion and hiding spots.

4. Bolivian Rams – Peaceful Cichlids That Get Along with Angelfish

• Share similar water conditions and a calm temperament.

• Stay in the lower levels of the tank, reducing conflict.

• Do not compete aggressively for food or territory.

5. Dwarf Gouramis – Colorful and Compatible with Angelfish

• Slow-moving and non-aggressive.

• Similar swimming patterns, making them a great match.

• Best kept in well-planted tanks with hiding spots.

Tank Setup for Angelfish and Their Tank Mates

Whether keeping angelfish alone, in pairs, or in a group, setting up the right environment is crucial for their well-being.

Tank Size

• Single angelfish: Minimum 20-30 gallons.

• Pair of angelfish: 30-40 gallons.

• Group of 4-6 angelfish: 55 gallons or more.

Water Conditions

• Temperature: 75-82°F (24-28°C)

• pH Level: 6.5-7.5

• Soft to moderately hard water

• Regular water changes to maintain water quality.

Hiding Spots and Decorations

• Use driftwood, rocks, and caves to provide hiding spots.

• Live plants like Amazon swords and Java ferns offer security and mimic their natural habitat.

• Keeping a well-structured tank reduces stress and territorial aggression.

Diet and Feeding

• High-quality flakes and pellets as a staple diet.

• Supplement with live or frozen foods like bloodworms, brine shrimp, and daphnia.

• Provide a varied diet to enhance coloration and overall health.

Challenges of Keeping Angelfish in Pairs

While angelfish pairs can be beautiful and fascinating to watch, there are some challenges to consider:

• Territorial Behavior – Pairs may become aggressive, especially during breeding.

• Breeding Stress – If a pair spawns, they may attack other fish and require a separate breeding tank.

• Pair Compatibility – Not all angelfish get along; some may fight even if paired.

Conclusion: Should You Keep Angelfish in Pairs?

Angelfish do not necessarily need to be kept in pairs to thrive. A single angelfish can live happily in a well-maintained tank with suitable tank mates. If you choose to keep a pair, ensure they are compatible and provide enough space to reduce aggression. For those who prefer a community setup, keeping a small group with other peaceful fish is often the best approach.

If you're wondering, "What Fish Can Go With Angelfish?", the key is choosing non-aggressive, similarly sized fish that share compatible water conditions. By understanding angelfish behavior and selecting appropriate tank mates, you can create a peaceful and visually stunning aquarium where your angelfish will flourish.
